Hello, There're cases when EDID may be present, but be just severely (or seemingly) broken. Is it possible to completely and unconditionally ignore any EDID info for KMS, and instead use user-supplied parameters? I googled the following message: http://www.mail-archive.com/dri-de...@lists.sourceforge.net/msg46741.html which suggested that it's possible, but I don't have any effect doing it myself.
It's also very hard to diagnose these issues. For example, mode selection is driven by EDID, but there're whole 0 occurances of that string in kernel dmesg. Passing drm.debug=1 starts to dump some internal registers, but still no hints which and why mode was selected. My specific issue is that there's an LVDS (of MSI X410/X430 notebook) which has right dimensions and refresh rate, but wrong, if not say unrelated, clock settings. The end result is that there's tearing-off, broken sync like on an old dying TV. More details are at http://wwww.ubuntuforums.org/showthread.php?p=10120939 . That's on 2.6.35 (stock Ubuntu 10.10 kernel). I was able to set CVT timings on X which gave stable picture, but no luck persuading kernel to do the same (I used video=LVDS-1:1366x7...@60 param, also tried more conventional modes like 1024x768). I'd appreciate any hints. -- Best regards, Paul mailto:pmis...@gmail.com _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/dri-devel
